  • Patent number: 9548312
    Abstract: A method includes providing a semiconductor structure including a nonvolatile memory cell element and one or more electrically insulating layers covering the nonvolatile memory cell element. The nonvolatile memory cell element includes a source region, a channel region, a drain region and a floating gate over at least a first portion of the channel region. A first opening is formed in the electrically insulating layers over the floating gate, a control gate insulation layer is deposited, and a second opening is formed in the electrically insulating layers over the drain region. The first opening and the second opening are filled with an electrically conductive material. The electrically conductive material in the first opening provides a control gate of the nonvolatile memory cell element and the electrically conductive material in the second opening provides an electrical contact to the drain region.
